Delivered in single cartons of surprising cardboard thickness—CD cover inserted for scale—dimensions of the extricated amps turned out to be 38 x 31 x 22.5cm WxDxH and weight 20kg. Instead of rubber footers, the 360 come with soft-nosed pointy metal couplers whose big knurled wheels make leveling easy. The insert shows two of them removed plus one of their fixed mounting bolts.


Removing the top's circumferential bolts and the four extra ones which are part of Goldmund's mechanical grounding scheme showed how three of those simply bear down on white Nylon standoffs. The last one couples cover and bottom plates with a metal rod like a quasi drain pipe. Whilst the nicely spiral-bound Telos 350 owner's manual included spoke of four toroidal transformers—the 360's manual hadn't returned from the printer yet—what revealed itself in the successor when I removed its rectangular black metal can (shown in the next insert) was a single Amplimo donut. With the trafo cover removed, the amp really did look mostly empty rather than stuffed to the gills. This reiterated the theme of cool cucumber operation.



The output transistors elude reviewer spy craft. That's because they mount beneath the vertical PCB directly to the right-sided finned heat sinks. If they dip into the same parts bin as the Job stereo and mono amps we reviewed, it'll be Exicon Mosfets. With the line voltage being selected inside to make for one global model, the 220V setting supports 211-257V, the 110V configuration 105-129V. Users with funky AC which runs under or over their country's specified voltage thus have about ±10% of wiggle room. As a DC-coupled circuit, one obviously wants to avoid funky preamplifiers which pass not gas but direct current. Regardless, Goldmund's hyper-quick protection circuitry promises to shut off the outputs to protect your speakers from such farts or any other error condition for worry-free use.


What should surprise the usual amp shopper about this rear panel are not the tightly spaced biwire terminals with Goldmund's customarily cheesy plastic nuts or the single analog RCA input delivered with an installed shorting plug. The real surprise are the coaxial i/o with the small digital/analog and left/right toggles. Since serial S/PDIF carries two-channel data, the coax out of one mono can connect to the coax in of the second whilst assigning the proper channel for this forward signal routing.


Three inescapable conclusions from this discovery were that, a/ the Telos 360 included a D/A converter; b/ since there was no provision for volume control, such a user had to fall back on digital attenuation inside computer software like PureMusic (or Goldmund's digital preamp); c/ Goldmund actually advocated a digital-direct hookup perhaps because over longer cable runs, they believe it causes fewer losses (which would echo Bel Canto).


[The super-imposed 'mechanical grounding' bolts aren't true to size but show the black version which connects to the metal rod; and one of the three silver ones which use Nylon rods. In actually, these obviously are inset into the top plate.]


The multi-pin port is for Goldmund diagnostics.


When Roy Gregory reviewed the Telos 200 for HiFi+ in 2009, a pair retailed for £12'000 (the British pound then had near perfect parity with the euro). Six years and four circuit generations later, the Swiss frank was on parity with the euro. Now a pair of Telos 360 demanded 39'950 Swiss, hence about three times as much. To fully warm to that takes about 10-15 minutes until the amps run at ca. 55°C. 1/8th output power into 8Ω draws 150 watts. Maximum power consumption is thrice that again. Max output before clipping swings 56Vrms or 285/450wpc into 8/4Ω (no 2Ω figure is given as we encountered already with the Job 225 and 250)*. Voltage gain is a high 35dB. Full bandwidth output noise with the RCA input shorted is <20µV. Dynamic range measured with a 22kHz flat bandwidth is 100dB RMS. Warranty bandwidth is 3 years parts and labour.

* Makers of truly load-invariant amplifiers usually take pride in publishing their 2Ω prowess, in some cases even 1Ω rigor. Vintage Krell springs to mind. The fact that Goldmund don't is suggestive. Already they're 120 watts shy of doubling into 4Ω. Earlier we looked at the toroidal power transformer and power supply. They were quite small considering. Owners of nymphomaniac speakers might thus pass. Think of big electrostats and ribbons and certain other humdingers which hit savagely below the impedance belt. Since I don't own such speakers—I tend to think of them as design flaws but won't fault someone who falls in love since love really is blind and free of judgment—this is mere supposition but still an educated one.
